Computer vision in Python with less than 10 lines of code

Detecto is a Python package for quick and easy object detection. Below are just a few of the features available:

• Train models on custom datasets
• Get all or top predictions on an image
• Run object detection on videos
• Save and load models from files

Detecto is built on top of PyTorch, meaning models trained with Detecto can easily be extracted and used with PyTorch code.

Usage and Docs

To install Detecto using pip, run the following command:

pip install detecto

After installing Detecto, you can train a machine learning model on a custom dataset and run object detection on a video with under ten lines of code:

from detecto.core import Model, Dataset, DataLoader
from detecto.utils import xml_to_csv
from detecto.visualize import detect_video

xml_to_csv('xml_labels/', 'labels.csv')
dataset = Dataset('labels.csv', 'images/')
loader = DataLoader(dataset)

model = Model(['dog', 'cat', 'rabbit'])
model.fit(loader)

detect_video(model, 'input_video.mp4', 'output_video.avi')

Visit the docs for a full guide, including a quickstart tutorial.

Alternatively, check out the demo on Colab.
